I placed a very high value order of $500 dollars for several M2 SSD. I chose the actual shop which is the one who makes the SSD, in order to not have a problem with the order. YET STILL, I received the order and one SSD is missing. After nearly a 45 min support chat with AliExpress, they made me file a dispute and give photo of the box and contents, which I did immediately while on chat. Very next day they make a decision on the claim as INVALID and DENIED, unless I can (and get this) obtain an official letter from the courier the seller used saying that the SSD was not in the package. Thats right the seller has to give ZERO evidence and is assumed to be 100% right if they say it. But the buyer has to prove it, and by means which they know FULL WELL is impossible to prove. I have now had to open a PayPal dispute, which I thank God I used. In one short word the AliExpress Disupte process is an ABSOLUTE JOKE, and is not worth anything to the buyer unless it is a 100% clear cut undeniable reason such as it was not shipped. In which situation it is still useless because there IS NO DISPUTE in that situation as the seller has no leg to stand on in the first place !!!! Take my advice (unless you dont mind loosing money), either dont use AliExpress or if you do pay via PayPal and / or credit card. So your protected against fraud / cheating.
